© 2017 ICIC International. This paper addresses the problem of distributed energy management system (EMS) design considering network-induced delays. First of all, the distribution power network incorporating solar panels is modelled as a discrete-time linear state-space equation and its measurements/control information is obtained using a set of sensors and actuators. These electronic devices send the observation information to the EMS via un-reliable communication links. In order to stabilize the system, we propose discrete-time distributed static output feedback control strategies based on the linear matrix inequality and semi definite programming approaches. Using the Taylor series method, delays are integrated into the closed loop system so that the proposed controller runs with less energy resources and computation. Simulation results demonstrate that the proposed method is able to stabilize the system in a fairly short time.
